50mm Expandable Polystyrene Sandwich Wall Panel

Excellent thermal insulation and heat preservation properties, reducing energy consumption costs

The thermal conductivity of EPS core material is extremely low (usually ≤ 0.041 W/(m·K)), far superior to that of traditional brick walls (thermal conductivity is approximately 0.81 W/(m·K)). It can effectively block the transfer of heat between indoors and outdoors, achieving energy conservation and environmental protection, and aligning with the concept of green and energy-efficient buildings.

Lightweight and high strength, reducing structural load

The density of EPS core material is only 8-28 kg/m³. When combined with metal panels, the overall weight of the panel is much lighter than brick walls of the same thickness (brick wall weight is approximately 190 kg/m³). This lightweight material can not only reduce the construction cost of the foundation but also avoid safety hazards caused by excessive structural weight. At the same time, the outer layer of the color steel plate has certain strength, with strong resistance to impact and deformation, capable of withstanding minor collisions during daily use, ensuring the long-term stability of the wall.

Outstanding sound insulation effect, enhancing space comfort

The internal structure of EPS core material is a closed honeycomb structure, which can effectively absorb sound waves and reduce noise transmission. The air sound insulation of ordinary EPS wall panels can reach over 40 dB. If double-layer core material or special surface layer design is adopted, the sound insulation can be increased to over 45 dB.

The EPS wall panels are widely used in the construction industry due to their lightweight, insulation, soundproofing, and fire-resistant properties. 

In industrial buildings, they are the preferred choice for industrial plant walls. Their light weight can reduce the load on the main structure and lower costs. Good insulation performance can reduce the energy consumption of air conditioning and heating, making them suitable for workshops with temperature requirements. Moreover, they are easy to install, which can shorten the construction period and meet the needs of enterprises for rapid production. 

In civil buildings, they are mostly used for low-rise residences, rural self-built houses, and prefabricated houses. The exterior walls have strong sound insulation, improving the living comfort; the interior walls can reduce the thickness of the walls and increase the usable area of the interior. Adding flame retardants, they reach B1 fire resistance level, comply with fire safety standards, have strong weather resistance, and can reduce maintenance costs later.
